What amp? The bulk of current 845/211 production is from Shuguang or PSVane/Acme. They make some very good products.
Elrog I hear makes good tubes. I have never heard them. I am thinking about starting to carry them.
Finally, KR produces a non-traditional 845 & 211. The filament current on the KRs is 1.0 amps vs. 3.5 amps. If your amp can handle them, they are pretty fantastic, but are not inexpensive. Art Audio amps accept them without modification due to our auto bias but a lot of amps need a resistor added.
